No, not quite true. (but a 1M KS would be hackable when its
available!)
The 3.1 kickstart is also 512K. The cool feature being that the
datapath to the roms is 32bits wide!
Kickstart being spread accross 2 x 128K x 16bits chips = 512K.
Thus an A1200 has a data path twice as wide (32) and twice as fast
(14Mhz) as A500-A1000-A2000 models, but still 512Kbyte.
